With the increasing move towards non-calculator papers in Scotland, and throughout the UK, pupils are now being examined on the most basic of mathematical skills. Fractions, Percentages and Decimals are often poorly understood by pupils who rely on calculators to complete their calculations. This book is designed to be used without a calculator, teaching these core mathematical skills so that pupils can face these papers with confidence. This Survival Guide is full of examples, exercises and summaries and at the end of each chapter, self-evaluation to ensure the skills have been mastered.
